在我们所面临的问题当中，我认为贫困是最大的问题。我的理由如下。
To begin with, there are still many people dying of starvation in many poor countries. They don’t have enough food, for they have no money. It’s no doubt that eating unhealthily will result in illness. What’s more, people in these undeveloped areas usually lack of proper health care. Thus, infectious diseases like AIDS spreads fast. That is terrible.
首先，在很多贫困国家仍然有很多人死于饥饿。他们没有足够的食物，因为他们没有钱。毫无疑问，饮食不健康会导致疾病。而且，这些不发达地区的的人们经常缺乏适当的健康检查。这样一来，像艾滋病这样的传染病就可以快速传播。多可怕的情况！
In addition, their clothes are too worn to be called “clothes”, and thus many of them are frozen to death. The little match girl in Andersen's fairy tale is just a case in point. Such a problem is mostly caused by lack of money, in other word, poverty.
其次，他们的衣服烂得不像衣服，很多人被活活冻死。安徒生童话里卖火柴的小女孩就是这样一个例子。这样的问题大部分是由于没有钱引起的，换句话说，是贫穷导致的。
From over above we can safely draw a conclusion that poverty is the biggest problem in Earth.
从上面我们可以得出一个结论，贫穷是地球上的最大问题。
